Question

Вирішіть будь ласка ось ці рівняня з хімії1.Cr+O₂=2.Cu+O₂=3.Na+O₂=4.Al+O₂=5.Ba+O₂=6.Cl₂+O₂=

Answer 1

4Cr + 3O2 = 2Cr2O3
2Cu + O2 = 2CuO
2Na + O2 = Na2O2
4Al + 3O2 = 2Al2O3
2Ba + O2 = 2BaO
Cl2 + O2 ≠ реакция не идет

Answer 2

1. Cr + O₂: The balanced chemical equation for the reaction between chromium (Cr) and oxygen (O₂) is: 2 Cr + 3 O₂ → 2 CrO₃ [[1]].

2. Cu + O₂: The balanced chemical equation for the reaction between copper (Cu) and oxygen (O₂) is: 2 Cu + O₂ → 2 CuO [[2]].

3. Na + O₂: The balanced chemical equation for the reaction between sodium (Na) and oxygen (O₂) is: 4 Na + O₂ → 2 Na₂O [[3]].

4. Al + O₂: The balanced chemical equation for the reaction between aluminum (Al) and oxygen (O₂) is: 4 Al + 3 O₂ → 2 Al₂O₃ [[4]].

5. Ba + O₂: The balanced chemical equation for the reaction between barium (Ba) and oxygen (O₂) is: 2 Ba + O₂ → 2 BaO [[5]].

6. Cl₂ + O₂: The balanced chemical equation for the reaction between chlorine (Cl₂) and oxygen (O₂) is: Cl₂ + O₂ → Cl₂O₂ [[6]].

Please note that these balanced equations represent the stoichiometric ratios of the reactants and products in the given reactions.
